Objective: To identify factors of oral health important for the final outcome, after secondary alveolar bone grafting in patients born with unilateral cleft lip and palate and compare occlusal radiographs with cone beam computed tomography (CBCT) in assessment of alveolar bone height. Design: Observational follow-up study. Setting: Cleft Lip and Palate Team, Craniofacial Center, Uppsala University Hospital, Sweden. Patients: 40 nonsyndromic, Caucasian patients with unilateral complete cleft lip and palate. Interventions: Clinical examination, CBCT, and occlusal radiographs. Main Outcome Measurements: Alveolar bone height was evaluated according to Bergland index at a 20-year follow-up. Results: The alveolar bone height in the cleft area was significantly reduced compared to a previously reported 10-year follow-up in the same cohort by total ( P = .045) and by subgroup with dental restoration ( P = .0078). This was positively correlated with the gingival bleeding index (GBI) ( r = 0.51, P = .0008) and presence of dental restorations in the cleft area ( r = 0.45, P = .0170). There was no difference in the Bergland index generated from scoring the alveolar bone height on occlusal radiographs as with the equivalent index on CBCT. Conclusion: Patients rehabilitated with complex dental restoration seems to be at higher risk for progression of bone loss in the cleft area. Supportive periodontal therapy should be implemented after complex dental restorations in cleft patients. Conventional occlusal radiographs provide an adequate image for evaluating postoperative bone height in clinical follow-up.

Objective To report the surgical outcomes of secondary alveolar bone grafting with premaxillary osteotomy in a single surgeon cohort of complete bilateral cleft lip and palate patients. Design Retrospective review of 44 consecutive patients using hospital notes and radiographs. Setting Single specialist cleft lip and palate center, UK. Patients Consecutive patients with complete bilateral cleft lip and palate who were being treated with secondary alveolar bone grafting incorporating premaxillary osteotomy. Outcome Measures Assessment of success of bone graft by Kindelan score; canine eruption; closure of fistulae and assessment of morbidity. Results Between January 6, 2000, and August 8, 2013, 44 patients with complete BCLP underwent secondary ABG with a premaxillary osteotomy as a one-stage procedure. The mean follow-up was 7.3 years (range 1.4 to 14.6). Eighty-five percent of ABGs were successful (a Kindelan score of 1 or 2), and canine eruption was 89%. Failure of the ABG occurred in 7%. Fistulae recurrence rate was 11%, all of which were asymptomatic. No premaxillae were devitalized. Conclusion Incorporating a premaxillary osteotomy into the secondary ABG surgical protocol can be a safe technique that gives excellent surgical exposure for fistula repair.

Objective To determine if secondary alveolar bone grafting (SABG) timing in patients with cleft lip and palate (CLP) influences the future need for additional maxillary advancement procedures, particularly Le Fort I osteotomy with rigid external distraction (RED). Design Retrospective cohort study. Groups were separated by SABG timing: early mixed dentition (ages 68 years) or late mixed dentition (ages 9-11 years). The criterion for RED was negative overjet ≥8 mm, and sufficient dental development for RED. Setting Single tertiary care institution. Patients Patients with CLP that underwent SABG from 2010 to 2015. Exclusion criteria included syndromic conditions, SABG surgery at age >12 years, current age <12 years, and <2 years follow-up. 104 patients were included. Main outcome measures The number of RED candidates and treated patients. Results There was no statistical difference in the number of RED candidates ( P  =  .0718) nor treated patients ( P  =  .2716) based on SABG timing; stratification by laterality was also insignificant. Early SABG is associated with higher odds of being a RED candidate (pooled, unilateral, bilateral) and treated patient (pooled and unilateral); however, there were no statistically significant associations between SABG timing and the number of RED candidates and treated patients as determined by logistic regression models. Conclusion There is no statistically significant association between SABG timing and the odds of being a RED candidate or treated patient. Future prospective studies are recommended to assess the relationship between SABG timing and maxillary growth in patients with CLP.

Objective To assess if a 4-point, radiographically based scale could be used between operators to reliably assess the success of secondary alveolar bone grafting. Design The study was retrospective with the clinicians blind to patient identity. Radiographs were examined twice by two clinicians with 1 week between assessments. Setting The research was carried out in a hospital-based orthodontic/oral and maxillofacial unit. Patients All patients who had secondary alveolar bone grafting in this unit between February 1992 and March 1995 were included In this study. There were 38 patients with a total of 48 grafted sites. Interventions The bone graft site was radiographed following orthodontic expansion prior to grafting. The radiograph was repeated postoperatively at a mean of 4 months after surgery. Main Outcome Measure The degree of bony fill in the cleft area was assessed using a 4-point scale: Grade 1 >75% bony fill; Grade 2 50–75% bony fill; Grade 3 < 50% bony fill; Grade 4 no complete bony bridge. Results Overall, 50% of grafts achieved grade 1, 23% were grade 2, 22% grade 3, and 5% grade 4. Levels of intra- and inter-observer agreement were highly variable (.33 to .72 kappa statistic). Conclusions The 4-point scale described could be used to assess the success of autogenous secondary alveolar bone grafting. It showed moderate to substantial intra-observer agreement, and fair-to-moderate inter-observer agreement.

Secondary alveolar bone grafting (SABG) is associated with donor site morbidities. We aimed to compare the outcomes of SABG and extensive gingivoperiosteoplasty (EGPP) at the mixed dentition stage. This single-blinded, randomized, prospective trial enrolled 50 consecutive patients with unilateral complete cleft lip and palate who had residual alveolar bone cleft, of which 44 (19 SABG, 25 EGPP) completed the study. Bone volumes before surgery, 6 months postoperatively, and 1-year postoperatively were compared using computed tomography. The Bergland scale score was recorded at 6 months postoperatively. Both groups had the same preoperative alveolar cleft volume. On the Bergland scale, 21, 3, and 1 patient in the EGPP group and 16, 2, and 1 patient in the SABG group were classified as types I, II, and IV, respectively, which did not show significant difference. With perioperative orthodontic treatment, the 1-year residual bone defect volume in both groups did not show significant difference (SABG 0.12 cm3 vs. EGPP at 0.14 cm3, p > 0.05). The study was not able to reveal much difference between SABG and EGPP combined with perioperative orthodontic treatment.

ABSTRACT Objectives: To measure the root lengths of maxillary central incisors (U1) and evaluate the relationship among U1 root length, tooth movement, and type of treatment appliance in patients with unilateral cleft lip and palate over a long-term follow-up period. Materials and Methods: Occlusal radiographs of 30 patients with unilateral cleft lip and palate, acquired less than 6 months before secondary alveolar bone grafting (SBG, T1) and after edgewise treatment (T2), were measured for U1 root length (R1 and R2, root lengths at T1 and T2, respectively). Frontal and lateral cephalometric radiographs acquired at eruption of U1 (T0), T1, and T2 were evaluated to determine the inclination and position of U1. Results: The average values of R1 and R2 on the cleft side were significantly lower than those on the noncleft side. Frontal cephalometric analysis revealed that the horizontal distance of the root apex from the median vertical line at T0 on the cleft side was significantly smaller than that on the noncleft side and was correlated with short U1 root length on the cleft side. On the other hand, R1 in patients treated with maxillary protraction appliances between T0 and T1 was significantly shorter than that in patients without maxillary protraction appliances. However, none of the changes in cephalometric measurements were correlated with root length. Conclusions: In patients with unilateral cleft lip and palate, the short root length of cleft-adjacent central incisors might be associated with the horizontal position of the root apex. In addition, orthodontic treatment with a maxillary protraction appliance before secondary alveolar bone grafting might be associated with short U1 root length.
